    The possibility to use three portable chlorophyll meters to estimate grain yield in rain-fed conditions
    (2021) Kızılgeçi, Ferhat; Yıldırım, Mehmet
    Handheld spectroradiometers are used to estimate the canopy's reflective properties, the condition of the plants. In this study, the potential use of three devices (SPAD, Greenseeker and CM 1000 chlorophyll meter) was compared that can estimate indirect the chlorophyll content of the leaves. The present research was established in four replications according to the randomized complete block design in the rain-fed conditions of Diyarbakir in the growing season of 2019. Seven barley cultivars were used as plant material. Chlorophyll measurements from leaves were taken in 2 different plant growth periods (anthesis and milky stage). Greenseeker showed changes between 0.51-0.75 in anthesis and 0.43-0.6 at milk stage. SPAD varied between 30-47.3 in anthesis and 27.6-46.7 in milk stage. CM1000 ranged from 217-548 in anthesis, 121-370 in milk. It was observed that the amount of chlorophyll in the leaf decreased in the milk period compared to the anthesis period. Significant regression relationships were determined with SPAD and greenseeker during anthesis R2 = 0.194* and greenseeker and grain yield at anthesis period R2 = 0.151*. As a result of the study, a significant relationship was found between only grain yield and greenseeker during the anthesis period under rain-based conditions. It has been observed that there is no relationship between other measuring portable devices and grain yield.

    Assessment of variety releasing performance from winter wheat germplasm at Diyarbakir condition
    (2021) Yıldırım, Mehmet; Kızılgeçi, Ferhat; Öztürk, Ferhat
    Spring wheat genotypes have been successfully grown with global climate change in the mate dominates. In the cold winter season, however, yield losses in spring wheat genotypes are occasionally reported. In order to solve this problem, wheat genotypes that are resistant to winter damage and suited for spring growing type must be identified. The focus of this research was to determine how winter ratio, plant height, spike length, spikelet number, spike grain number and grain weight variability of 50 wheat genotypes were ranged between 157.2- 494.7 kg da-1, 9.33-14.57 %, 82.7-88.9 %, 56-102.3 cm, 6.3-12.5 cm, 13.8-23.6, 30.6-64.4 and 28.2-56.6 g, respectively. The findings suggest that there is a large genetic variation in the traits studied, and that suitable wheat genotypes can be discovered either directly or through breeding research. According to the cluster analysis, clustering the genotypes by cutting the dendogram into 6 groups will improve genotype selection for hybridization and allow for more genotypic variation to be benefited from. The significant association between protein content and grain yield suggests that high-yielding and high-quality cultivars can be identified. The parameters controlling the grain number have a favorable impact on grain yield, while grain weight has a negative impact, according to the component analyses. The findings suggest that winter wheat trial sets can be used to identify genotypes suitable for spring type conditions.

    AGRONOMICAL, MORPHOLOGICAL AND PHYSIOLOGICAL RESPONSES TO HEAT AND DROUGHT STRESS IN WHEAT: A REVIEW
    (2022) Kızılgeçi, Ferhat
    Wheat (Triticum aestivum L.) is one of the crucial crops in the world in terms of economy, production, food, and nutrition (Yilmaz et al.2022). Wheat is grown in over 220 million ha of land all over the world, where it is subjected to abiotic stress on average (Paudel et al., 2021). This accounts for approximately 30 percent of the world's total cereal area (Cossani and Reynolds, 2012). FAO estimated that annual cereal production must increase by nearly a billion tons in order to feed the projected population of 9.1 billion people in 2050. The 21st century requires an increase in crop production and productivity to meet the rising demand for food (Iqbal et al., 2017). Wheat is cultivated in the tropics and subtropics, where it is subjected to a wide range of abiotic pressures. Crop yields are drastically diminished due to adverse environmental stress (Rahaie et al.,2013). The most common abiotic stresses are heat, drought, salinity, cold, chemicals, and excess water. But heat and drought are the main abiotic stresses that affect wheat production around in the world (Liu et al., 2016; Kizilgeci et al., 2017). Considering global climate model, the average worldwide temperature is projected to have risen by 6 degrees Celsius by the end of the twenty-one century (De Costa, 2011).

    Recent trends show reductions in crop productivity worldwide due to severe climatic change. Different abiotic stresses significantly affect the growth and development of plants, leading to decreased crop yields. Salinity and drought stresses are the most common abiotic stresses, especially in arid and semi–arid regions, and are major constraints for barley production. The present review attempts to provide comprehensive information related to barley plant responses and adaptations to drought and salinity stresses, including physiological and agronomic, in order to alleviate the adverse effect of stresses in barley. These stresses reduce assimilation rates, as they decrease stomatal conductance, disrupt photosynthetic pigments, reduce gas exchange, enhance production of reactive oxygen species, and lead to decreased plant growth and productivity. This review focuses on the strategies plants use to respond and adapt to drought and salinity stress. Plants utilize a range of physiological and biochemical mechanisms such as adaptation strategies, through which the adverse effects can be mitigated. These include soil management practices, crop establishment, as well as foliar application of anti-oxidants and growth regulators that maintain an appropriate level of water in the leaves to facilitate adjustment of osmotic and stomatal performance. The present review highlighted the adverse effect of drought and salinity stresses barley and their mitigation strategies for sustainable barley production under changing climate. They review also underscored that exogenous application of different antioxidants could play a significant role in the alleviation of salinity and drought stress in plant systems.

    Improving grain yield, protein ratio and nitrogen use efficiency of durum wheat (Triticum Durum Desf.) hybrids using spad meter as a selection criterion
    (2019) Kızılgeçi, Ferhat; Akıncı, Cuma; Yıldırım, Mehmet
    Chlorophyll content can serve as a guide for nitrogen management in agricultural systems. Hence, the investigating leaf chlorophyll in crops could be of benefit to boost production. The present study evaluated 15 different hybrids of durum wheat (Triticum durum Desf.) combinations in F F and F generations for nitrogen use efficiency (NUE), grain yield and 3, 4 5 protein content using chlorophyll meter index (CCI) under three different nitrogen levels (0, 120 and 240 kg N/ha). The results showed that N levels significantly influenced the grain yield and quality traits of durum wheat genotypes, and accordingly, SPAD readings could be used as an indirect selection criterion in durum wheat breeding to achieve the desired production targets. Genetic correlations among grain yield, CCI, grain nitrogen yield (GNY) and protein were high in F generation under high nitrogen regimes. It was also observed that all the generations of Zenit × Menceki, 3 Mersiniye × Menceki, Zenit × Mersiniye, Mersiniye × Spagetti and Spagetti × Menceki crosses have high yield potential and yield stability. It was concluded that the evaluation of the segregation populations at different generations in the same year and selection in the later generations might make a significant contribution to reduce the costs

    (2019) Kızılgeçi, Ferhat; Albayrak, Önder; Yıldırım, Mehmet
    The present study was undertaken to identify the best durum wheat genotypes suitable for the South-Eastern Anatolia Region of Turkey with desirable grain yield and quality. In the context, thirteen spring durum wheat genotypes were evalu ated in four environmental condition of the target region in consecutive two growing seasons in the year 2013-14 and 2014-15. The stability and supe riority of genotypes, and favorable testing environ ments were described by using ANOVA and GGE biplot analysis (genotype, genotype x environment). Genotype, environment and GEI (genotype x envi ronment interaction) was found to be highly signifi cant for multiple traits. The total variation of PCI (principles component) and PC2 was calculated 90% for ETI (environment trait interaction), 57.35 for GTI (genotype trait interaction), and 87.5% for GE interaction. The results of total variation of ETI was found higher than GTI and GEI. On the other hand, the biplot analysis showed that four mega environments occurred among ETI and three envi ronments (E1, E2 and E3) correlated with different traits, while environments E4 did not correlated with any traits. The environment E1 was found the best for Grain yield, test weight, thousand kernel weight and starch content, E2 for L*, b*, SPAD, and E3 for zeleny sedimentation, protein content and wet gluten content. In the biplot analysis, the environments divided three sector based on traits. Among the genotypes, the genotype G8 was per formed the best in all tested environments, while G9 was found the best based on all traits. The re sults of the study showed that GGE biplot analysis can be used as a good tool to identity of the most suitable environment in terms of all the characteris tics as well as to identify the best genotypes for future breeding program.

    STABILITY EVALUATION OF BREAD WHEAT GENOTYPES UNDER VARYING ENVIRONMENTS BY AMMI MODEL
    (2019) Kızılgeçi, Ferhat; Albayrak, Önder; Yıldırım, Mehmet; Akıncı, Cuma
    Stable and high yield varieties identification under various conditions prior to release as a varie ty is the main steps for breeding program. In order to exploit narrow and broad adaptability of geno types and assess their effects, environment and GE interaction, 12 spring bread wheat genotypes were grown at four various experimental locations during 2013-14 and 2014-15 growing seasons. The stabil ity and superiority of genotypes were identified by the AMMI (additive main effect and multiplicative interaction) and GGE (genotype, genotype x envi ronment) biplot analysis. The AMMI analysis showed that the variance of genotype, environment and GE interaction were significant and the major treatment sum of squares were significantly affect ed by environments (85.47%), genotypes (8.51%) and GE interaction (6.07%). On the other hand, the first principal component axes (PCA 1) distributed to the complete interaction as 62.56%, and the second PCA 2 axes 37.44%. The GGE bi-plot anal ysis indicated that the total variation PC (principle component) was 83.09%, and PC1 was accounted as 63.69%, PC2 only 19.40%. The AMMI analysis showed that C11 was quite stable as well as the highest yielder among test genotypes, while C7 and C8 were unstable and low yielding across environ ments. The GGE biplot indicated that it was detect ed in two mega-environments, and the first mega environment covered three environment (E1, E2 and E3), and the second mega-environment covered only E4. The genotypes C11 and C12 remained superior under ME I, while genotypes C1, C3 and C5 were for ME II. Among the genotypes, the gen otype C1 may be recommended to be developed and released as an approved cultivar for being com paratively more stable and the highest yielder. Therefore the AMMI and GGE biplot models have an opportunity to determine the best genotypes under multiple environments considering on adapt ability and stability concentrating on overall per formance for screening superior genotypes.
